Description

Inverter arc welding power source, also known as arc welding inverter, is a new type of welding power source. This kind of power supply generally uses three-phase power frequency (50Hz) AC network voltage, which is first rectified and filtered by the input rectifier to become DC, and then passed through high-power switching electronic components (thyristor SCR, transistor GTR, FET MOSFET or IGBT). The alternating switching function is to invert the intermediate frequency AC voltage of several kHz to several tens of kHz, and at the same time reduce the voltage to several tens of V suitable for welding through the transformer, and then rectify and output a fairly stable DC welding current through the reactance filter.

Function: manual arc welding, steel bar butt welding

Applicable industry: steel plate, Architectural Engineering etc
